In this paper, a robust power control system for the nuclear reactor using the Quantitative Feedback Theory method (QFT) is presented. A nonlinear uncertain dynamic system with different working condition has been considered for the nuclear reactor. To design a robust control system for the nuclear reactor, two different controls oriented linear models have been identified. The nonlinearity and uncertainty of the system are modeled as uncertainty for a nominal LTI system. The QFT controller has been designed and simulated to control the reactor power. The proposed control system has a favorable performance over the wide range of reactor operating conditions and can easily be implemented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
